' This 'invntion relates to ccuplings for pump rods such 'as are used to connect windmill ump r'o'dswith the sucker rods of ordinary armpunip's.

In the use of far n pumps windmills are frequently e n lc ye d to "drive su h pumps,

the driving being effected through a long cpit an or ump rod extending from the crank shaft of the windmill dow through the tower to the pump and coupled at its lower end to thefsu'oker rod of the pump itself; All such pump are mostuniversal- -"lyprovided with anordinary hand lever for operating the pump at such times when lack of wind preventse pump operation by windmill. To usethe h-and 'power it is co1nmm to disconnect the windmill pump rod from the sucker rod of the pump. Couplings have been devised for this purpose and are 'fre'quentlyin 'the fofrm of straps and bolts, or, at other times they have a socketlike arrangement of one type or other. Straps and bolts,-oi course, are d'ifiicult for a single person to manipulate and any socket arrangement is not only diilicult for .a single vperson to .use, but even where two people are using the arrangement accidents are apt .to occur by the fingersof one of the opera tors being caught in the socket, owing to the windmill turning over otwind or the like. v

The important objects ofthe present in vention'are'to provide a ewform of coupling, by mean'sofwh'icha windmillpump rod and the suckerrod of a pump may be quickly connected or disconnected; the connecticn being eiiected without the use of u'ch as must be used with bolts andnuts; theconnection being made by lateral movement and thusbeing free from thedanger of pinching-the finger between the ends of thetwo rods as they move together; and the entire, coupling being, of such nature as to be readily applied to any ordinary pump and windmill I With the above and other objects in view theinvention consists in generalof a novel form of rod coupling having improved arrangement of parts and details, one preferred form of which willnow be described and specifically claimed, reference being had drawings wherein: Figure 1 is a-side view of the lower part of awindmill showing the coupling in use Fi ure 2 is a section on the line 2-2 of.

'i ;t11e.present disclosureth'ere is shown a well casing or top 10 whereon is mounted a pump 11 having the usual pump or sticker is a section-onthe line 7- of rod 1'2 and being provided with an ordinary pump handle 13 for manual operation when s iowing. there having a pitm'an 15, the arrangement being tl'rat described in my copending application filed of eve'nid'a'te herewith, and bearing the Serial Niunber 32,944, and being here shown for the purpose of illustrating howth'e present"device maybe combined with that shown in said co'pe'nding application; The

lower part oi the windmill is indicated at 16 and the lower part 'otthe rod at 17. The upper part of the tower and the operating mechan sm for the -cd 17 are of any well knowntype and are-not deemed necessary here to be shown. I p V 1 I p 7 he {rod 1 7 's of the fusualformbeing square in crosssectlon and the rod 12 is also of the usual form, rectangula i cross 5,

tion. The coupling itself includes a body portion 18 havingprojecting tr'o'inoneside a pairof parall'e flanges 19betw ee'nwhich is received the'rod v 17, the face of the body portion being provided with teeth 20 tobite into the wooden'rod At each side of the body there is provided an elongated eye 21 and these eyes receive the ends of a U-bolt 22 which e'r'nbracesthje ma-17 and clamps the samefirm'l'y against the body 18, nuts 23 of the ordinar kind being em loyed on the threaded legs of the l l bolts." By this means thefc'oupling is firmly fi'x d to the lower end of the rod 17 p Projecting"- from the opposite side of the body 18 is a second pair of flanges 24, between which may fit the upper" end of the rod 12. The body 18 projects downwardly" ahlc opening in the downwardl t projecting end oi? the hod v and has on one end a cylindrical head 26 which lies hetween the flailges ill, its other end being" provided with the usual nut 27. Projecting laterally from one of the flanges ill a boss or sleeve 28 wherelhrough extends a pivot holt .29 on which is pivote 'l one end oil a. cover plate or keeper plate 30, this plate heing ol such length as to swing, in closed position. across the channel formed between the flanges 24-. On the edge oi the flange opposite the hoss 28 is a. lip 31 notched to receive the hottom edge oi the keeper plate upon the latter being moved to said closed position. This keeper plate is preli'erahlv arranged so as to cover the end of the pin head 26 when closed and is provided with a knoh or handle 32 to enablev it to he moved between open and closed positions. The plate is likewise provided with a stop lug 33 :l'or limiting its opening movement.

ll ith this construction the rod 12 is provided with an opening 54 to lit the pin head 26 and in connecting the two rods 17 and 11.2 the keeper plate 30 is thrown back to dotted line position, as shown in Figure 3 and the pin head 26 slipped into the open ing 34-. The keeper plate is then moved to the closed or full line position, shown in the same figure and thus the two rods are firmly secured together. hviously disconnection may he elieeted by simply throwing the keeper plate to open position and slipping the pin head 96 out of the opening 3%.

OllVlOUSlV the coupler may be varied in its shape and proi'iortion to suit different shapes or rods and other minor variations may he made as will not efl'ect the scope of the invention. Accordingly it is not desired. to confine the invention to the specific form here shown, hut it is desired to inelnde all. forms as may properly come within the scope claimed.

Having thus described the inventioin what claimed as new, is:

l. A coupling tor windmill and pump rods comprising a hody portion having a pair of flanges projecting from one lane to receive the end of a windmill rod and asecond pair oi flangi es projecting; from the other tare to receive the upper end oil a pump red. a connecting pin projecting lrom the last mentioned face hetween said flanges to engage in an opening in the pump rod. and a keeper plate pivoted to one of the last mentiimml Flanges and norn'ially bridging the space hetweeu the last mentioned pair of flanges: to retain the pump rod between said, flanges.

.3. A coupling for windmill and pump rods comprising a body portion having a pair ot flanges projecting from one face to receive the end. oil a windmill rod and a second pair of flanges projecting from the other face to receive the upper end of a pump rod, :1 connect ing pin projecting 'lrom the last mentioned 'tace hetween said flanges to engage in an opening in the pump rod, a keeper plate pivoted to one ol the last mentioned flanges and normallv lnidging the space hetween the last mentioned pair of flanges to retain the pump rod hetween said flanges, and a lip on the second of the last 1nentioned pair of flanges to support the free end ol the plate in bridging position.
